👉 A semiligneous is a type of structure that can be defined as having both a topological and geometric properties. It is often associated with algebraic structures, particularly in the context of Lie algebras and Lie groups. In algebraic geometry, a semiligneous structure is one where every point has an open neighborhood homeomorphic to the unit ball of a complex vector space. This can be seen as a generalization of the idea of "semilocular" which refers to a
